I'm running CentOS 5.3 and would like to know what the "best" or "proper" method is to build a custom kernel using the generic kernel sources from kernel.org. Most of the references I've found talk about modifying the current CentOS kernel using the RPM way. I really want to have the latest kernel due to some important security issues that haven't been addressed in the current CentOS 5.3 kernel.
View 6 RepliesI'd like to create a custom squeeze kernel. Is it a really bad idea to edit to edit the kernel config file directly instead of using "make config", "make menuconfig" or "make gconfig"? My problem is I missing a search function, for example in "make menuconfig" and cannot find some entries.

Is this the correct way:
I need to install Ubuntu on approximately 50-60 netbooks. None of them have CD drives, and I don't want to have to install them individually, walking around with a USB stick. I figured the fastest way to install on so many machines is to use a combination of apt-cacher (http://www.debuntu.org/how-to-set-up...ith-apt-cacher) and netbooting. I have successfully booted one machine to test, but as soon as the kernel comes up, support for the network interface is gone. Specifically, the "atl1c" module is not included on the netboot initrd image. Also, I would like to try to use preseeding, and I need to get that onto the initrd as well.
So, to summarize my question: How can I create a custom install kernel and initrd? I have a feeling it's related to the "debian-installer" category in the package repository, but I have not found any good documentation about doing this.
I have a problem with my custom kernel when I want to create the Nvidia kernel module.After this finished I installed the image and headers and created the Nvidia kernel module. Everything worked fine.However, if I remove the linux-source from my home directory then I can't create the kernel module.Even though I have the headers for the kernel installed.

(i think, that it is not ok, because when i build the same version of kernel on x86_64 platform, after rpmbuild command i have kernel, kernel-devel and kernel-headers packages) My CentOS version is 5.2; platform i686; kernel, kernel-headers, kernel-devel packages 2.6.18-92.el5.

I have read that when using xfs with lvm2, prior to kernel 2.6.29 write barriers are by deffault disabled.As i want to migrate /home to xfs (and create a external partition to hold some data in xfs too) i was thinking in compile a custom kernel 2.6.30 or higher from [URL].I have read the wiki, all the warnings , and that for compile a kernel.org kernel you should use the Linux Kernel in a Nutshel guide/book. But i don't really know if would worth do that only to have write barrier support , more when in one month i will buy a ups to be sure i can shutdown the pc well if the power goes out.Should i enable write barriers on xfs with lvm2 ,although going to have a ups ?

I am a newbie to CentOS. I use CentOS5 for NetFPGA project.
I installed everyone except building driver for NetFPGA hardware. When I enter the "make" command, it gives an error like:
make: *** /lib/modules/2.6.18-238.12.1.el5.centos.plusxen/build: No such file or directory. Stop.
In the manual, it says that:
-If you get an error message such as "make: * /lib/modules/2.6.9-42.ELsmp/build: No such file or directory. Stop.", then kernel sources are need to build the driver.
But I don't know which package I have to install. My kernel version is 2.6.18-238.12.1.el5.centos.plus-i686.
I am running an Hp Pavillion dv6000 with the Broadcom card that never seems to work for Linux. I recently talked with my friend who said he found a way to get it work.following his instructions I opened Synaptic and checked the package bmcwl-kernel-source to be installed.I went through the process of it all and it said it had install successfully. I restarted the computer and when I tried to enter my operating system I got this error "Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block(8,1)"
I have previous versions of Linux on my computer so I can still get in to those if need be but I don't know how to undo what I did or why it isn't working for that matter. Does anyone have any ideas as to why I am getting this error and how I can fix it?
I've been trying to install nvidia drivers yesterday, so I went to runlevel 3, ran the .bin installer and it came up with error: missing kernel-devel and kernel-source.
So I go yum install kernel-devel, it does, but it doesnt find anything like kernel-source.
How do I fix this issue? I have Fedora 12, and I ran drivers from:[URL]..
I installed the latest kernel liquorix (2.6.35) but when i want to install the Nvidia driver downloaded on the Nvidia website (256.53), i have an error message because Nvidia doesn't found the kernel source tree.
I install linux-image-2.6.35-6.dmz.2-liquorix-686_2.6.35-16_i386.deb, linux-headers-2.6.35-6.dmz.2-liquorix-686_2.6.35-16_i386.deb and build-essential. I don't understand why the installation doesn't works.
It sounds like he's making a difference between the kernel "source code" and the kernel itself(as in the downloaded file/ files) but the way he talks about both is the same.So then, if one had already "installed" the "kernel sources code," why would he need the "tarball with the newest Linux kernel?" He's already "installed" a kernel, right?

so im assuming the less amount of system overhead is to run it as IDE?I have no issues running it either way I just want to do whats right.. and what is going to be supported in kernels down the line, as im considering a bump from my current 2.6.30 kernel upwards for my project.
